The Wodehouse error which I made was due to his books having been written so long ago. I made an assumption, which was corrected at the time, that they were public domain. Strangely, some of his books are in the MR library, but not the Blandings novels. (Note: I haven't recently checked this, they may have been removed.)

Wodehouse's books which were published prior to 1923 are in the US (and only the US) public domain.
